The search for new effective methods of preventing or reducing ischemic myocardial injury is an actual problem of modern experimental and clinical medicine. The aim of the study was to determine the reproducibility of antiischemic and antiarrhythmic effects of remote ischemic preconditioning myocardium during ischemia-reperfusion of old rats. It was found that the remote ischemic preconditioning is effective in terms of necrosis area size limits in the left ventricle during ischemia-reperfusion in old rats. Remote ischemic preconditioning in old rats during ischemia-reperfusion has no antiarrhythmic effect. The findings indicate the need for a differentiated approach to the appointment of remote ischemic preconditioning in patients with acute myocardial infarction. The existence of such a risk factor for cardiovascular diseases as age can be a criterion for exclusion remote ischemic preconditioning as a way of reducing arrhythmias in old patients with ischemia-reperfusion injury.
